Can I save money by flying with a stopover to South America?
Yes — for South America you can often save by taking a stopover: 1-stop fares start from around £685, compared with about £698 to fly direct. The trade-off is a longer total journey with a connection, so weigh the saving against the extra travel time. If budget matters more to you than speed, a 1-stop option is worth considering.
How far in advance should I book a flight to South America?
To get a below-average price to South America, aim to book roughly 26 weeks before departure, when fares tend to dip to around £842. Leaving it to the final week is usually the most expensive time to buy, costing about 9% more, as availability tightens. Booking extremely far ahead isn't always cheaper either, so a few weeks to a couple of months out is typically the sweet spot.

About flights to South America
Overview of flying to South America
South America is a continent of dramatic contrasts — the Andes and the Amazon, vibrant cities and golden beaches, ancient ruins and world-famous festivals. For UK travellers it's a bucket-list region for culture, nature and adventure, reached via direct or one-stop flights to its major gateways.
Best time to visit
Seasons are reversed from the UK. The dry season (roughly May to September) suits the Andes and much of the continent, while December to February is warm and lively in the south. Fares rise around Carnival and the festive season — the price charts on this page show the cheapest dates.
Popular countries & cities
Brazil (Rio, São Paulo): beaches, cityscapes and Carnival.
Argentina (Buenos Aires): tango, steak and elegant boulevards.
Peru (Lima, Cusco): gateway to Machu Picchu and the Andes.
Colombia (Bogotá, Cartagena): colonial charm and Caribbean coast.
Chile (Santiago): wine country, deserts and Patagonia.
Airlines and routes
British Airways and LATAM fly direct from London to São Paulo and Buenos Aires; connecting options include TAP Air Portugal (via Lisbon), Iberia (via Madrid), Air France (via Paris) and Avianca, serving UK airports including Manchester.
Top tips for finding cheap flights to South America
Book roughly 2–4 months ahead for long-haul value.
Avoid Carnival and the festive season if your dates are flexible.
Compare direct and one-stop European routes.
Midweek departures often beat weekend fares.
Travel essentials
Visa rules vary — UK travellers often don't need one for short tourist stays, but always check each country's rules before you fly.
Currencies differ by country; carry the local currency for each destination.

Packing & baggage tips
Full-service carriers (e.g. British Airways, Turkish Airlines, KLM) usually include a checked bag on long-haul economy fares; basic/low-cost fares often don't.
Cabin (hand) bag size is commonly around 56 × 45 × 25 cm — confirm your airline's limit before you pack.
Liquids in hand luggage must be in containers of 100 ml or less, inside one clear resealable bag.
Weigh your bags at home — airport excess-baggage fees are far higher than pre-booked allowances.
Extra or heavier bags are almost always cheaper added online in advance than at the airport.
